Abstract
An arrangement for recirculation of exhaust gases of a supercharged combustion engine includes a return line for recirculating exhaust gases, an air-cooled EGR cooler and a bypass line having an extent such that it can lead recirculating exhaust gases past the EGR cooler. A valve is operable to be placed in a first position to lead the whole flow of recirculating exhaust gases through the EGR cooler during situations where there is no risk of ice formation in the EGR cooler, and in a second position to lead the whole flow of recirculating exhaust gases through the bypass line during situations where there is risk of ice formation in the EGR cooler.
